I just deleted over 2000 spam account requests. There could possibly have been some legit accounts in there too, but I'm not going to try to weed through 2000 account requests in order to find a few legit ones! Sorry. That's why I created the two step account request procedure described in the first post to this thread.

Most likely two of my friends had account requests in that batch. I told them to email you, but I don't think they understood. Obviously there's no way you can sift through 2000 accounts and identify the good ones unless you know what usernames to look for. I'll get back to them and hopefully they'll get back to you.

Check this out! Here is a thread on a mod you can install that asks a question you have to answer properly before it will let you register. The guy also has an interesting story of what he's gone through and finally said he switched to vBulletin, a paid software.
